I bought two cases: the Bluecell RX100 Black color PU leather classic and the Tenba Mixx Pouch Large. Check Amazon. The Bluecell is a retro case that seems well made. I can imagine myself using it when I want to look retro AND have the camera on a neckstrap. One has days like that. Also, with the cover off, the remaining leather bottom makes it easy to hold this slippery little camera.

The Tenba is a belt mount elastic nylon bag. I leave the wrist strap on the camera, hanging out of the bag so it's the first thing I grab and put on as I take the camera out. Also, this bag is elastic enough that I can leave the Clearviewer on the camera. This is the bag I'll use the most.
